The Town of Hamburg police department confirmed the version presented by the two sources, telling 2 On Your Side the perpetrator was the first person to enter the office, just before 35-year-old Laurence Wells walked in during the early morning hours of Saturday, June 29. Police said they still have no suspects in the murder, and they also said they have not received any hits on their DNA samples.

Police have not released the surveillance video to the public, but they did release multiple still photos of the suspect on the scene. They said they have sent the surveillance content to the FBI -- an assisting agency in the case -- to enhance the photos. At that point, they said they may ask for the public's assistance in identifying the suspect.

Police said they are not ready to yet make a determination as to why the suspect was in Wells' office. They said they are still investigating whether the suspect was waiting for Wells and knew he'd enter at that specific time, or if he was attempting to rob the store and then killed Wells to stop the encounter. Police did say they do not believe anything was stolen from the store at this point.

One of the sources told 2 On Your Side that another office next to Wells' had money locked in a safe, and police confirmed that fact. Police said the suspect only entered Wells' office during the break-in.

Police also said they are investigating the possibility that the killer had inside knowledge of the store's layout, although they said it is possible that information was provided unknowingly.
